Unlock the science of nickel, from cutting-edge awaruite flotation in ultramafic deposits to its critical role as an essential plant micronutrient. This episode explores how weakly acidic conditions and desliming techniques optimize nickel recovery for clean energy technologies, while also revealing how nickel activates urease, a key enzyme in nitrogen metabolism. Learn how pH, mineral composition, and serpentine slimes impact both industrial processing and biological systems. A must-listen for anyone interested in mineral processing, agriculture, and environmental science.
